Case #350 – June, 2013

A 45-year-old man with travel history to Ghana presented to his health care provider with recurrent fever and chills. He admitted to not taking any kind of malaria prophylaxis during his travels. Blood smears were prepared, stained with Wright’s stain, and examined. The laboratory initially reported Plasmodium falciparum but requested confirmation from a reference laboratory, so the slides and EDTA blood were sent to the CDC-DPDx for diagnostic assistance. Figures AI show what was found on one of the stained thin smears. What is your diagnosis? Based on what criteria? What, if any, other tests would you recommend?
